.SH DESCRIPTION
-.B Pick
+.B pick
searches within a folder for messages with the specified
contents, and then identifies those messages. Two types of search
primitives are available: pattern matching and date constraint
.B \-after
and
.B \-before
-switches take legal 822\-style date
+switches take legal RFC 822\-style date
specifications as arguments.
-.B Pick
+.B pick
will default certain missing
fields so that the entire date need not be specified. These fields
are (in order of defaulting): timezone, time and timezone, date, date
and timezone. All defaults are taken from the current date, time,
and timezone.
.PP
-In addition to 822\-style dates,
+In addition to RFC 822\-style dates,
.B pick
will also recognize any of
the days of the week (\*(lqsunday\*(rq, \*(lqmonday\*(rq, and so on),
also honor a specification of the form \*(lq\-dd\*(rq, which means
\*(lqdd days ago\*(rq.
.PP
-.B Pick
+Use the
+.BR \-reverse
+switch to make
+.B pick
+find matching messages in reverse order, working from the highest message
+number down to the lowest. This can be useful in for searching recent
+messages in large folders, for example,
+.PP
+.RS 5
+.nf
+pick\0\-reverse\0\-from\0frated\0|\0xargs\0\-n1\0scan
+.fi
+.RE
+.PP
+.B pick
supports complex boolean operations on the searching primitives
with the
.BR \-and ,
same way
.B mark
uses them.
+.PP
+The
+.B \-debug
+switch causes pick to output a representation of the search
+pattern.

+is used in a backquoted operation, such as
+.PP
+.RS 5
+scan\0`pick\0\-from\0jones`
+.RE
+.PP
+and
+.B pick
+selects no messages (e.g., no messages are from
+\*(lqjones\*(rq), then the shell will still run the outer command (e.g.,
+.BR scan ).
+Since no messages were matched,
+.B pick
+produced
+no output, and the argument given to the outer command as a result of
+backquoting
+.B pick
+is empty. In the case of
+.B nmh
+programs,
+the outer command now acts as if the default `msg' or `msgs' should be
+used (e.g., \*(lqall\*(rq in the case of
+.BR scan ).
+To prevent this
+unexpected behavior, if
+.B \-list
+was given, and if its standard output is not a tty, then
+.B pick
+outputs the illegal message number \*(lq0\*(rq
+when it fails. This lets the outer command fail gracefully as well.

The pattern syntax \*(lq[l-r]\*(rq is not supported; each letter to be
matched must be included within the square brackets.
